Here are some pics of my quail shelf unit in progress. The top when attached will parallel with the top so that bottom slopes 290mm to 320mm with a roll out egg space of about 30mm. The eggs should hopefully roll out onto an extended wire base. I hope to make a total of four shelves. But will make one shelf first to see how it works out before making the other three. Unfortunately I keep stuffing up on the door no matter what I do I cannot get it square. I now have a rhombus with uneven mitre joints hopefully gluing together to make a door. The shelf unit was reclaimed from my sisters work place.
